Candwax 7.6x7.6 cm pillar candles have an incredible burning time of 40 hours! To make such slow burning candles we choose high-quality wax, 100% natural cotton wicks, and hundred variations to test. We want to provide you only with the best experience of use. So we try to do our best while creating tall candles smokeless. We also do not paint our ivory dinner candles, you will see that they are solidly colored all the way through.
